php - Create tournament fixture lists -

-

i need figure out how solve this:

we trying create fixture list tournament, below find table generated webinterface have. (not sure if ideal layout make fixture list, may changes store , use basis task below).

the tournament concept x number of courts in same location. have court utilization close 100% possible. problem generate fixture list based on table without conflicts( team plays 2 games in same round) , have best utilization of courts.

explanation of concept: tournament_id id of main tournament. have sub tournaments, , identified pool_id. each pool may have several groups play round robin (single/double) group_id. have done setup of games teams playing each other located in home , visit, , round within group indicated round. means if group has 2 games in round 1 maximum games can played in group round, if 1 game maximum 1.

priority used this: equal priority means games should handled during creation of fixture list. in example pool_id=23 has 3 groups, 0,1,2. 1 , 2 has priority 1, , 0 has priority 2. means games group 0 cannot played before games in priority 1 groups 1 , 2 has been played. (it used keep control inside each pool.)

the number of courts in tournament known @ stage , example it's 4.

i able generate fixture list in 2 different ways:

1: use courts column , assign correct court.

2: not use courts column, , assign games next available court.

i have array can loop through make fixture list, game game, round round indication of court assigned.
